![[screenshot of Emacs package manager description of bln-mode package]
Navigating the cursor across long lines of text by keyboard in Emacs can be cumbersome, since commands like ~forward-char', ‘forward-word', and ‘backward-word' move sequentially, and potentially require a lot of repeated executions to arrive at the desired position. This package provides the binary line navigation minor-mode (~bln-mode'), to
address this issue.
It defines the commands ~bln-forward-half' and ‘bln-backward-half', which allow for navigating from any position in a line to any other position in that line by recursive binary subdivision.](https://pbs.twimg.com/media/E_DLzHgUUAAoUXu.jpg)

With today's tech, you could probably have a keyboard binding for "move the cursor to where I'm looking". (Pointing is slow!)
Some people I know only navigate by search. Their expert skill is finding a small string that's discriminatory for the desired spot, then "Ctrl+S <string>" and you're there.

See also vim's EasyMotion/Emacs' avy-mode: type the first 1-2 letters at the spot you want to go & it overlays unique short labels on every matching spot. Then you type the label to jump to. 4-6 strokes to get anywhere on screen.https://github.com/abo-abo/avy

You just reminded me that for years I used Conkeror, a keyboard-based browser (based on Mozilla xulrunner). You'd press "f" (for "follow") and it would number all the links on the page like this:pic.twitter.com/ALBY77vYwT
